Whether, and to what extent, behavioral anomalies uncovered in the lab manifest themselves in the field remains of first order importance in finance and economics. We begin by examining behavior of retail traders/investors making investment decisions in constructed laboratory markets. Our...

Deferred Acceptance (DA), a widely implemented algorithm, is meant to improve allocations: under classical preferences, it induces preference-concordant rankings. However, recent evidence shows that--in both real, large-stakes applications and experiments--participants frequently play seemingly...

The favorite-longshot bias describes the longstanding empirical regularity that betting odds provide biased estimates of the probability of a horse winning--longshots are overbet, while favorites are underbet. Neoclassical explanations of this phenomenon focus on rational gamblers who overbet...

Neoclassical theory postulates that preferences between two goods are independent of the consumer's current entitlements. Several experimental studies have recently provided strong evidence that this basic independence assumption, which is used in most theoretical and applied economic models to...

What explains the mixed evidence from laboratory tests of Kőszegi and Rabin's (2006 and later) model of expectations-based reference-dependent preferences? We investigate one hypothesis: to become (behavior-affecting) reference points, probability beliefs have to sink in--being merely lagged,...

We document that prior portfolio choices influence investors' expectations about asset values, and their future choices. We find that people update more from information consistent with their prior choices, leading to sticky portfolios over time. These effects are related to how the brain's...

Models of reference-dependent preferences propose that individuals evaluate outcomes as gains or losses relative to a neutral reference point. We test for reference dependence in a large dataset of marathon finishing times (n = 9,524,071). Models of reference-dependent preferences such as...
